A former Aurora high school security guard is scheduled to appear in court next week on charges related to a sexual assault of a student.

Broderick Lundie, 29, faces charges of sexual assault of a child by a person in a position of trust and sexual assault involving a 10-year age difference, according to records in Arapahoe County District Court. Lundie allegedly had oral sex and exchanged nude pictures with a student at Grandview High School during the 2017 spring semester, according to his arrest affidavit.

Lundie, who was arrested May 4 at the Aurora Police Department, no longer works at the school, said Abbe Smith, a spokeswoman for the Cherry Creek School District. As a security specialist, he was a school district employee.

Lundie is the son of Overland High School principal Leon Lundie, Smith said.

Lundie courted the student through Instagram, according to police records. The conversations at first were casual but turned romantic in nature and then moved to personal text messages, police said. Lundie allegedly sent the female student pictures of his erect penis, and she sent him pictures of herself in her underwear and of her bare breasts, the affidavit said.

Lundie later met the student at her house when her parents were not home. She got in his car, and they drove around the block where they allegedly performed oral sex on each other, the affidavit said.

Other girls reported that Lundie had contacted them on Instagram, including one student who said the security guard had made her feel uncomfortable, the affidavit said. Police never charged Lundie in connection with contact with other students.
